3.Typical steam boiler with connections available below the water line (Refer to Figure 9).

a.The Alliance™ connection labeled "BOILER RETURN" should be piped to a tapping in the boiler that is below the lowest permissible water level. The use of unions, a shut-off valve, and a drain valve is recommended for future service convenience. The use of a flow control or check valve is required to prevent back flow through the water heater during operation of the space heating system.

b.The Alliance™ connection labeled "BOILER SUPPLY" should be piped to a tapping in the

boiler section furthest away from the return tapping to prevent short circuiting in the boiler. This tapping should be high enough to provide hot water but must be below the lowest permissible water level. The water heater circulator should be floor mounted with full size (1" minimum) piping from the boiler and no flow restrictions in this piping. Be sure the flow arrow on the circulator points toward the water heater. The use of a union, shut-off valves, and a drain valve is recommended for future service convenience. The use of an in-line "Y" style strainer is required to prevent accumulation of sludge in the water heater's coil.
